Research Abstract

A decoupling and matching network in very effective for a small terminal antenna used in a MIMO system. However, design formulas for the network elements have not been explicitly reported. We have derived the design formulas for the elements of the mesh network and succeeded in realizing the independent property of the feeding terminals of the multi-beam antenna with mutual couplings. Design formulas for the simple decoupling network composed of transmission lines and bridge susceptances have been generalized to cover the wide range of MIMO antenna. We have also presented to evaluate the MIMO antenna for the frequency characteristics of the radiation efficiencies.
